Abstract: A method for producing a thermal infrared sensor array in a vacuum-filled wafer-level housing with particularly small dimensions, consisting of at least two wafers, a cover wafer and a central wafer comprising multiple infrared-sensitive sensor pixels on a respective thin slotted membrane over a heat-insulating cavity is disclosed. A method for producing a high-resolution monolithic silicon micromechanical thermopile array sensor using wafer level packaging technology, wherein the sensor achieves a particularly high spatial resolution capability and a very high filling degree with very small housing dimensions, in particular a very low overall thickness, and can be inexpensively produced using standard CMOS processes. This is achieved in that the cover wafer is first rigidly mechanically connected to the provided central wafer comprising the sensor pixels with the infrared-sensitive pixels by means of wafer bonding, and the central wafer is then thinned out from the wafer rear face to a specified thickness.

Abstract: The present disclosure provides a radiator assembly that includes a stationary assembly that includes a fan assembly coupled to a fan frame assembly, a rotating assembly that includes a radiator frame assembly and a support frame assembly coupled to the radiator frame assembly, and an actuation assembly coupled to the rotating assembly. The rotating assembly may be rotatably coupled to the stationary assembly and configured to rotate relative to the stationary assembly in a first direction and a second direction opposite the first direction. The actuation assembly may be configured to enable and limit rotation of the rotating assembly relative to the stationary assembly in the first direction and the second direction.

Abstract: The invention provides a system and a method for detection of oil spills and icebergs at sea and for aiding the navigation of ship traffic to avoid collisions between ships and icebergs. A constellation of polar orbiting satellites is used to determine the position of icebergs and oil spills within an observation area, and this information is transmitted to a data processing center which also receives information concerning the position of ships within the observation area. The data processing center uses this information to evaluate the likelihood of collisions between ship and icebergs and sends warning signals to the ships, alerting them to the danger. The data processing center also correlates the position of ships and oil spills to determine the likely cause of the latter.
